Anton Dohrn habitats/biotopes
Data collected aboard the MV Franklin in July 2009: Acoustics (Multibeam echosounder), Drop camera/towed video (10 sites).
The original survey plan (Stewart 2009) for the Anton Dohrn Seamount AoS involved a combination of radial transects on the top of Anton Dohrn and a suite of transects parallel to the flanks of the seamount both at the top of the flank and a level near the base the flank tohighlight the lower level of possible rock or hard substrate.
The survey plan was subsequently modified to provide an area of multibeam coverage over two areas on the flanks of the seamount. The areas selected were on the south-eastern flank and the northwestern flank (Figure 5) and included diverse morphological features noted during the SEA 7 2005 survey (Jacobs 2006). The areas would provide a contrast between the south-eastern area primarily subject to southern water masses and the north-western area occasionally influenced by ÔÇÿcolderÔÇÖ NSDW waters spilling over the Wyville Thomson Ridge. The two case study areas also differ in the height of the cliff surrounding the seamount. In the northwestern area the break in slope is at around 845m below sea level with the cliff descending to the moat at around 2195m depth, the slope levels off below 1700m at the foot of the cliff.
The south-eastern area shows a subtle break in slope at around 875m below sea level and a major break in slope at around 1100m below sea level before the cliff descends towards the centre of the moat at around 2300m water depth. The range of morphological features observed on the lower slopes of also differed. Both the original biotope map showign Annex I habitats and a translated EUNIS version are available.
